·         CZPT Keyless Locking Devices are utilized in rotating machinery,  making clamping strain between surface area of locking device and shaft to develop adjustable and releasable mechanical link,  so as to clamp gears,  pulleys and other factors to a shaft CZPT threads or keys. 
Materials of CZPT Locking Device are offered in:
Carbon Metal S45C, C45E, 1045, 40Cr, 42CrMo4V  
Stainless Steel AISI431, AISI304
·         CZPT Machinery Timing Belt Pulleys and Toothed Bars/ Timing Bars. 
Normal and non-normal pulleys according to drawings are available. 
Components of CZPT Timing Belt Pulleys are available in:
AlCuMgPb 6061 6082 CZPT Timing Pulley
C45E 1045 S45C Carbon Steel Timing Pulley
GG25 HT250 Cast Iron Timing Pulley
SUS303 SUS304 AISI431 Stainless Steel Timing Pulley
Other content on demand, this kind of as cooper, bronze and plastic
·         CZPT Jaw couplings are made as 3 piece blend,  which includes two hubs and 1 elastomer made of polyurethane.  The curved jaw matches onto the spider,  which minimizes shock to the motor and other delicate equipment.

In a twin pulley system, this ratio is equal to the reference diameter of the output pulley getting increased than the reference diameter of the enter pulley. It’s reasonably uncomplicated as prolonged as you calculate the equipment ratios for a more sophisticated pulley method stage by phase. For several pulleys, the ratios of the numerous parts of the system have to be calculated to decide the total ratio. In the photo above, the reference diameter of the lower drive wheel is 20mm, the radius of the upper wheel is 40mm, and the ratio is 2:1. 2 spins on the reduced wheel and 1 spin on the upper wheel. The gear ratio also tells us something about the torque of the program since the ratio of output torque to input torque is equal to the gear ratio. For that reason, the torque used to the upper wheel is two times as fast, but the velocity is halved.
